MOUNTING FOR SOUND-REPRODUOING, MACHINES.

Laiaoie.

Specification of Letters Patent.

Application filed October 4, 1920. Serial No. 414,520.

To all whom it may concern:

Be it knownthat I, EUGENE ONEILL, a citizen of the United- States, residing at Minneapolis, in the county-of Hennepinand State of Minnesota, have invented certain new and useful Improvements inMountings for Sound-Reproducing Machines; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same. 7 v

This invention relates to a mounting orcabinet for sound reproducing machines particularly designed to be used in sales rooms.

As is well known, the records for these machines are now sold in very large numbers. The customers purchasing the records usually wish to hear them played in the sales room. It has been the common practice heretofore to provide booths in which a machine will be located and in which thecustomer may listen to a record played thereon. These booths are required in consider-- able numbers and occupy much floor space.

As the sales rooms are located largely in downtown stores where floor space is very expensive, the erection of. a large number of these booths has become a serious item of expense. Even with a large number of booths, itis often impossible to" accommodate" all of the customers desiring to'hear a record played. It is an object, therefore, of this invention to provide amounting for a sound reproducing machine which is of small dimensions, as compared with a booth, and by-means of which a customer can satisfactorily listen to the record being played without disturbing or being disturbed by another customer who is also listening to a record. 1

It is a further object of the invention to produce sucha mounting in a simple and inexpensive'manner. v 1

Other objects of the invention will appear as the description proceeds in connection with the accompanying drawings, in which like reference characters refer to the same which v Fig. 1 is a View in front elevation of the device with some parts broken away;

Fig. 2 is a side elevation of the device, as viewed from the right of Fig.1, also having :ome parts broken away and shown in sec F 3 is a toppla'n view thereof;

Fig. 4 is a view mostly in section of a portion of the sound transmitting tube; v

Fig. 5 is asection on the line 55 of Fig. l; and

Figs. 6 and 7 show modifications in section of the'elbow shown in Fig; 4:. 7

Referring to the drawing, the device is seen to consist of a cabinet A comprising a closed box which is adapted to contain a talking or sound reproducing machine B, and means for conveying the sound to the ears of a customer.

The cabinet A comprises front walls 1, side walls 2, a bottom 3, and a top portion 4. The top portion 4 has, doors 5 hinged thereon which extend for almostthe full width of the cabinet and, to a considerable extent, lengthwise thereof. When. these doors are closed, the cabinet A forms a box which is almost, ifnot entirely, sound proof.

Disposed within this box is the usual'sound reproducingmachine B having thereon the usual turn table 6. Reproducing and sound conveying arms 7, are mounted in the bracket.

cated in the rear of the cabinet. This hollow post has'a chamber 10 therein and a pipe or tube 11 is firmly secured in saidfpost to communicate with opening 10 and projectsa slight distance above the top of the cabinet. A vertical tube 12 is arranged to telescope over tube 11 and to be vertically adjustable thereon. This tube 12 carries what may be referredto generally "as a listeningfdevice G.

This listening device G comprises the tube 12, which tube-has a horizontal portion 13 extending across the top thereof. and communicating' therewith. Telescoping over the ends of member 13 and forming a swinging joint therewith, are the elbow members 1 f whose free portions project vertically. The Kmember C- has dependingtubes 15 which telescope over the free ends of member 1 1.

Each of these tubes comprises a vertical portion 15*,- a curvedportionj15 which curves outwardly from member 13 and which is re- .versely curved into a U-shaped band 15.

free end of these tubes and slidable thereon are ear pieces 18 which have sleeves 19 embracing said tubes.

Disposed in the member 13 between the members 14 is a cylindrical valve member 20 having a handle 21 thereon arranged to slide in a slot 22 in the member 13. This valve is arranged to rotate in the-member 13, and as is clearly shown in Fig. 5, when thehandle 2]. is'turned entirely to the right in said figure, will close theopening betweenmembers 13 and 12. p

In Fig. 6, is shown a modification of the elbow member 14 and in this modification,

the elbow part proper is made in a separate piece 25 and a tube 26 corresponding with theupper part of tube 1 1- telescoped thereover. i

In Fig. 7, is shown a modification in which the tube 26 is disposed inside of an elbow member 27 The usual crank for winding up the sound reproducing machine B is shown as 28, which crank projects outside of the cabinet. ,At one side of the machine B the cabinet A is provided'with a record rack 29 in which any desired records may be kept.

It will be seen that the listening device'C is adjustable vertically and is also adjustable axially of the tube 11, so that it can be turned thereon to any desired angle. The-member 15 and members 14 can also beturnedangularly on member 13, as shown in dotted lines in Fig. 2. As stated, the ear pieces 18 are also adjustable onthe free ends 16 of member 15.

The cabinet A is provided with suitable legs 30 and the cabinetsare designed to be arranged adjacent one, another to form a counter, the customers side of which is the one near the device C, while the sales side is the one'disposed oppositely thereto.

When a customer desires to hear a record played, the device C will be adjusted so that the ear pieces 18.are brought into comfortable relation to the customers ears. The doors 5 willthen be-opened and the record placed upon turn table 6 and the machine started- As the box l'is substantially sound proof and the ear pieces 18 contact the customers ears, practicallyno sound will be transmitted into the sales room and a customer will not be disturbed by other records being played, nor will the playing of the record to which he is listening disturb others.

Theloudness of the tone of the machine can be varied by adjusting the valve 21 to suitthe desire of the customer.

It is further pointed out that an important I feature in applicants device consists in the fact that the tubes conveying the sound are telescoped into each other-in the direction in which the sound is to travel. In other words,

at every joint, the sound emerges from the inside tube into the outside tube Asa'result, none of the sound volume 1s lost, or

passes out through the telescoping joints,

which loss would occur ifthe tubes were disposed in the reverse manner. As shownin Fig. 6, this arrangement can still be earned out by using the reduction elbow 25. In the arrangement shown in Fig. 7, the sound passes from the elbow 27, into a smaller tube 26. If it is desired to. use an elbow of uni-' form dimension, as shown at 27, there will be no air or sound leakage as the olnt between members If preferred, the machine 13, or. a series 26 and 27 is a tight rigid joint.

thereof, may be constructed to be driven by 1 and set forth in theappended claims.

What I claim isi 1. A sound reproducing machine mount-' ing for salesrooms having in comblnation, a

support adapted to receive the motor cabinet and turntable of a sound reproducing machine, a post on said support enclosing a chamber, atone arm mounted onh'said post with which said last mentioned chamber Generally stated, the invention consists of the structure shown and described communicates, and, a listening device mounted on said support and also communicating with said last mentioned chamber.
